SilentS, провел повторные замеры. звук брал с USB DAC (80%громкости) и принимал через линейный вход материки
Parameter Value Description
-------------------------------------------------------------------
fs 46,4 Hz free air resonance frequency
Zmax 57,5 Ohm impedance at resonant frequency
Rdc 4,1 Ohm DC-resistance
Qms 11,08 mechanical Q of the speaker
Qel 0,84 electrical Q of the speaker
Qts 0,78 total Q of the speaker
Mms 68,0 g extra mass (pretended)
Vb 60,0 dmІ test volume (pretended)
Mmd 66,30 g mass of driver*s cone
Cms 0,18 mm/N compliance of driver*s suspension
Vas 24,91 liter compliance volume of the speaker
Vas was determined with the elasticity of the membrane
значения меняются при изменении уровня громкости входного сигнала(линейного входа). Я понизил до 80%
